9 R. c. BOREE LOCK HOOK Filed Oct. 25, 1944' q 2 Sheets-Sheet 2 Inventor character'com'prising ,dppliciationbctober 2 The present invention relates tonew and'user ful improvements in hooks for various purposes. and has for its primary object to "provide, ,in a manner as hereinafter set forth, a device of this novel locking means- Another very important object'of the invention is to provide a'hook of the aforementioned character which may be readily opened while under greatlstrain for releasing the load when desired.

Other objects of the inventi'on'are to provide a hook of the character described which will be comparatively simple in construction, strongldurable,ihighly efficient and reliable in'u'se, compact, and-Whichmay be manufactured at low cost. g All of the foregoing and still further objects and advantages of the' invention willlbecome apparent from a, study of the following pecification, takeninconnection with the accompanying 3,395,999; 1 I I r cx 'nook fierce, Jaeksoiiville'; F I I 3, SQTilEIgNO-f. l an... v of. 294 1 83 if is ,1 to besuspendedEby swinging latch 111's lever 9." Adjacent thexconcave face 6'- on the tail-6' of the hook 3 is an in- .clinedface ill-which is adapted for abutting engagement with the underside of the lever 9 a'dl'acerit its junction With the latch T- 1.11: is thought that the :manne inwhich the device" is used/will-be.readilyapparent from a consideration of the foregoing. 1

Briefly; the. chain, rope or cable isiattachedto ,the device through theb'ushing :4 andthe device is thus suspendediin so that ,theihoo'k3i will hang inopen position by gr vity: and the'; l atch. I hangs loosely-sibetween the plates J and 2. on the bushing 4.1.. When a load the :hook; the eye or bail attached to ,the :load' is; movedgupwardly against drawings, wherein-like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in side elevation. Figure 2 is a view in front elevation of the device.

Figure 3 is a vertical sectional view, taken substantially on the line 3-3 of Figure 2.

Figure 4 is a side view, showing the hook open.

Figure 5 is a view in vertical section throughthe open hook.

Figure 6 is a view in the upper end portion of the Figure '7 is a view in the lower portion of the device.

Referring'now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated spaced, opposed, elongated plates l and 2 of suitable metahsaid plates being longitudinally curved and of substantially the shape shown to advantage in Figures 1 and 5 of the drawings. A-tubular rivet or bushing 4 connects one end portion of the plates l and 2. The other end'portions of the plates l and 2 are connected by a solid rivet 5. Journaled on the rivet 5 and cooperable with the inwardly curved edges of the plates l and 2 for retaining the load is a hook 3. Formed integrally with the pivoted end of the hook 3 is a tail member 6. a

A metallic latch I is journaled on the bushing 4 for swinging movement between the plates I and 2. The convex face B-of the swinging latch I is engageable with the concave face 6 of the transverse section through device.

' tail 6 for releasably securing the hook 3 in closedmoveme t cau s, th co cave:

the leg of the U hetwe nthe side l b i hqu ithe r v t thereof; engages the -shaped book 3 .which operates plates l and hand swings, the 5. so "that the tail: portionv 6 latch fl. Further, upward B to ride over the convex face 8 of the latch until downward movement of engagement of the lever 9 with the inclined face transverse section through comprises a pair of ID on the tail 6 of the hook 3. Inasmuch as the concave face 6' is concentric with the axis of the bushing 4 and the convex face 8 follows the contour of the concave face 6' it will be obvious that release of the latch from hook engaging position may be readily achieved by lifting the lever 9.

As best seen in Figure l of the drawings, the

plate 2 i comparatively narrow and shaped to expose th major portion of the lever 9. Thus, access may be readily had to the lever for manually swinging the latch! upwardly so as to disengage the concave face 6 from the convex face 8, thereby permitting the hook 3 to swing to open position. The comparatively wide plate I functions as a guard or shield for the lever 9 when the latch I is in closed or inoperative position, thereby preventing accidental disengagement of said latch from the hook.

It is believed thatthe many advantages of a hook constructed in accordance with the present invention will'be readily understood, and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.
